Physical Assembly Mapper: A Model-Driven Optimization Tool for QoS-Enabled Component Middleware

This paper provides four contributions to the study of optimization techniques for component-based Distributed Real-time and Embedded (DRE) systems. First, the authors describe key challenges of designing component-based DRE systems and identify key sources of overhead in a typical component-based DRE system from the domain of shipboard computing. Second, they describe a class of optimization techniques applicable to the deployment of component-based DRE systems. Third, they describe the Physical Assembly Mapper (PAM), which is a model-driven optimization tool that implements these techniques to reduce footprint. Fourth, they evaluate the benefits of these optimization techniques empirically and analyze the results.
